Ambiq Apollo2 Blue Ultra Low Power MCU adds Bluetooth Connectivity

Ambiq Micro unveiled their ultra-low power Apollo MCU back in 2015 with claims of Cortex-M4 performance at Cortex-M0+ energy efficiency by leveraging SPOT (Subthreshold Power Optimized Technology) technology that allows operating the microcontroller at very low voltages (less than 0.5V). Since then the company introduced Apollo2 MCU with 10 μA/MHz power consumption, but still a generic purpose microcontroller.

Earlier this year, the company unveiled a new version of Apollo2 microcontroller adding Bluetooth connectivity, and allowing Bluetooth applications that last years on a charge. Meet Apollo2 Blue.

The company also offers Apollo2 Blue EVB for development with Arduino headers. The Atmel processor is used for debugging purpose. and if you are looking for Apollo2 Blue MCU it’s the small black chip in the top right corner area. You’ll find more details about the MCU and development kit including datasheet, schematics, PCB layout, and getting started guide on the product page.

Typical applications would include any battery powered device requiring Bluetooth connectivity such as smart watches, wireless sensors, activity and fitness trackers. home automation, wireless mice and keyboards, alarms and security system, and others.
